Laravel Advanced Wheres how to pass variable into function?

Questions:

Example in doc:

DB::table('users')
        ->whereExists(function($query)
        {
            $query->select(DB::raw(1))
                  ->from('orders')
                  ->whereRaw('orders.user_id = users.id');
        })
        ->get();

But what if I need to use external variable like that:

            ->where('city_id', '=', $this->city->id)
            ->where(function($query)
                {
                    $query->where('name', 'LIKE', '%'.$searchQuery.'%')
                    ->orWhere('address', 'LIKE', '%'.$searchQuery.'%')

                })

For now I created new property and accessed it through $this->, but is there any more convenient way?

Answers:

You can pass the necessary variables from the parent scope into the closure with the use keyword.

For example:

DB::table('users')->where(function ($query) use ($activated) {
    $query->where('activated', '=', $activated);
})->get();

More on that here.

If you are using Laravel eloquent you may try this as well.

$result = self::select('*')
                    ->with('user')
                    ->where('subscriptionPlan', function($query) use($activated){
                        $query->where('activated', '=', $roleId);
                    })
                    ->get();

@kajetons’ answer is fully functional.

You can also pass multiple variables by passing them like: use($var1, $var2)

DB::table('users')->where(function ($query) use ($activated,$var2) {
    $query->where('activated', '=', $activated);
    $query->where('var2', '>', $var2);
})->get();

You can pass variables using this…

$status =1;
 $info = JOBS::where(function($query) use ($status){        
         $query->where('status',$status);
         })->get();
print_r($info);
